UpdateProgressOverlayExtender Error when ControlToOverlay Changes Size


I am wondering if anyone can give me any advice on a problem I am having with the UpdateProgressOverlayExtender. It is working perfectly 99%, but on one of my pages, I am making heavy use of ajaxToolkit CalendarExtenders. When the panel with the CalendarExtenders loads in a UpdatePanel, the UpdatePanel changes size but the UpdateProgressOverlayExtender does not. This looks really bad until the Async postback finishes and the UpdateProgressOverlayExtender stops working its magic.
Has anyone seen this before ? Any suggestions ?

I was able to get a screenshot of the problem. The screenshot was taken just after the new updatepanel contents loaded (which changed the size of the updatepanel), but before the UpdateProgressOverlayExtender finished.

Please help.

I should add one more thing. I do not see the problem when runner from my local dev machine. I only see the problem when it is hosted on my server. This makes it very difficult to debug.
